Embodiment
Spring operating mechanism embodiment of the present invention:
The functional part be connected with connecting lever 1 in spring operating mechanism comprises cam, locking bolt, output pull bar, snap close bearing pin and splined shaft.Wherein, except connecting lever 1 unlike the prior art except, miscellaneous part can with reference to the structure shown in figure 1.
As shown in Figure 3 and Figure 6, connecting lever 1 comprises connecting lever body 11, locking bolt block 12 and roller 13; Connecting lever body 11 comprises rivet 112, the connecting lever sheet 111c being located at rivet 112 two ends, the spline stiffening piece 113 being located at the ring-type on splined hole 117 edge, roller axle 115 and location six square shafts 116 that the axis as connecting lever supporter extends along connecting lever body thickness direction;
Every three of connecting lever sheet 111c fits into a connecting lever sheet group, and be respectively connecting lever sheet group 111a and connecting lever sheet group 111b, both are in rivet 112 two ends respectively; Locking bolt block 12 is between two connecting lever sheet groups, plays a supportive role; Connecting lever sheet group 111a and connecting lever sheet group 111b both sides are equipped with spline stiffening piece 113, and spline stiffening piece 113 is fixed in two connecting lever sheet groups by bolt mode; Adopt spline stiffening piece 113 can improve the intensity of splined hole 117; Connecting lever sheet 111c, spline stiffening piece 113 are stamping parts, once formed in punching course splined hole 117 along and appearance profile, this reduces processing cost;
In order to make roller 12 freely rotate, rivet 112 and roller axle 115 are all made the Step Shaft that the two ends diameter of axle is thin, the interlude diameter of axle is thick, and the length of the axis of the two interlude is greater than the thickness of roller 13 axis;
The axis of locating six square shafts 116 extends along connecting lever body 11 thickness direction, it is simultaneously through each connecting lever sheet 111c and each spline stiffening piece 113, accordingly, connecting lever sheet 111c and spline stiffening piece 113 have the hexagonal hole with location six square shaft 116 location fit, hexagonal hole can in connecting lever sheet 111c and spline stiffening piece 113 stamping process simultaneously once-forming; Locate the screw thread that six square shaft 116 1 is provided with bolt, other end is provided with block disk; Positioning action can be played to connecting lever sheet 111c and spline stiffening piece 113 at employing location six square shaft 116 like this, prevent from occurring misplacing between connecting lever sheet 111c and between connecting lever sheet 111c and spline stiffening piece 113, improve positioning precision.
